Do Speech Therapists Worldwide Use a Standard Milestone Guideline?

Do you know if your child is hitting the milestones or not? It's a loose guideline. You have to understand that this is not a perfect standard. A person like me versus a younger therapist who just came out of school versus a very senior therapist. We all have different standards, right? And that's because I've seen children at my age and at a certain time frame between 2014 till now, whereas a senior therapist, they started in 1980s, until now, the children they see. Back in the day, ABC was apple, banana, carrot. Right? Now it's alligator, beef, binoculars or something. It's very different nowadays, the therapists who have just graduated, they have learned a new set of standardized tools and tests and whatever as well. There's also trilingualism. Gulism is on the rise. All of us have very different standards.
